Stop thinking in
''this is the plattform I'm working for''

but instead of

''I'll give my skills and knowledge to support the fediverse''

And it could start with simple changes like mentioning the fediverse within the landingpage. And that this plattform is part of a wider movment.
Maybe also designing a recognizable logo, which could work soon or later as a kind of quality #badget.

don't be centristic about your #plattform be #fediverse
